Any malware exists with the only target – gain money on you1. And the programmers of these things are not thinking of morality – they use all possible ways. Taking your personal data, receiving the comission for the promotions you watch for them, exploiting your hardware to mine cryptocurrencies – that is not the full list of what they do. Do you like to be a riding steed? That is a rhetorical question.

What does the notification with Behavior:Win32/ScriptLaunchMsiexec.A detection mean?

The Behavior:Win32/ScriptLaunchMsiexec.A detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware program is good at scanning, however, prone to be generally unstable. It is prone to malware attacks, it has a glitchy user interface and bugged malware clearing features. Therefore, the pop-up which states concerning the ScriptLaunchMsiexec is rather just an alert that Defender has actually recognized it. To remove it, you will likely need to make use of another anti-malware program.

The exact Behavior:Win32/ScriptLaunchMsiexec.A infection is a really nasty thing. It sits into your computer disguised as a part of something legitimate, or as a piece of the program you have got on a forum. Then, it makes everything to weaken your system. At the end of this “party”, it injects other viruses – ones which are wanted by cyber burglars who manage this malware. Hence, it is almost impossible to predict the effects from ScriptLaunchMsiexec actions. And the unpredictability is one of the most upleasant things when we are talking about malware. That’s why it is rather not to choose at all, and don’t give it even a single chance to complete its task.

Is Behavior:Win32/ScriptLaunchMsiexec.A dangerous?

As I have actually specified before, non-harmful malware does not exist. And Behavior:Win32/ScriptLaunchMsiexec.A is not an exception. This malware modifies the system settings, modifies the Group Policies and Windows registry. All of these things are critical for proper system functioning, even when we are not talking about Windows safety. Therefore, the virus which ScriptLaunchMsiexec contains, or which it will inject later, will try to get maximum profit from you. Crooks can grab your personal information, and then sell it on the Darknet. Using adware and browser hijacker functions, embedded in Behavior:Win32/ScriptLaunchMsiexec.A virus, they can make profit by showing you the ads. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is hard to trace the sources of malware on your PC. Nowadays, things are mixed, and spreading methods chosen by adware 5 years ago can be utilized by spyware nowadays. But if we abstract from the exact distribution method and will think about why it has success, the answer will be really basic – low level of cybersecurity understanding. Individuals press on ads on strange websites, open the pop-ups they receive in their web browsers, call the “Microsoft tech support” assuming that the scary banner that says about malware is true. It is essential to know what is legitimate – to stay away from misunderstandings when attempting to identify a virus.

Nowadays, there are two of the most extensive ways of malware spreading – bait e-mails and also injection into a hacked program. While the first one is not so easy to avoid – you should know a lot to understand a counterfeit – the 2nd one is simple to get rid of: just don’t utilize hacked apps. Torrent-trackers and various other providers of “free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway point of malware. And Behavior:Win32/ScriptLaunchMsiexec.A is simply within them.

How to remove the Behavior:Win32/ScriptLaunchMsiexec.A from my PC?

Behavior:Win32/ScriptLaunchMsiexec.A malware is incredibly difficult to remove by hand. It puts its documents in several places throughout the disk, and can get back itself from one of the parts.
